Chrysanthemum named ‘Hoggar’

ABSTRACT

A Chrysanthemum plant named &#39;HOGGAR&#39; characterized by its medium sized blooms with yellow ray-florets and yellow-green disc florets.

BACKGROUND OF THE INVENTION

‘HOGGAR’ is a product of a breeding-program which had the objective ofcreating new chrysanthemum cultivars with a daisy type flower, a 7 weekresponse and a medium plant height. The new plant of the presentinvention comprises a new and distinct cultivar of Chrysanthemum plant.‘HOGGAR’ is a seedling from a cross in a breeding program maintainedunder the control of inventor. The female parent is#93.1028—unpatented—, the male parent is #93.0910—unpatented—, bothunamed seedlings not available to inventor for description. The new anddistinct cultivar was discovered and selected as a flowering plantwithin the progeny of the stated cross by Rob Noodelijk in a controlledenvironment (greenhouse) in Rijsenhout Holland in April 1998. The firstact of asexual reproduction of ‘HOGGAR’ was accomplished when vegetativecuttings were taken from the initial selection in July 1998 in acontrolled environment in Rijsenhout Holland.

SUMMARY OF THE INVENTION

The present invention is a new and distinct variety of chrysanthemumbearing medium sized blooms with yellow ray-florets and yellow-greendisc florets.

BRIEF DESCRIPTION OF THE DRAWINGS

The present invention of a new and distinct variety of chrysanthemum isshown in the accompanying drawings, the color being as nearly true aspossible with color photographs of this type.

FIG. 1 shows a plant of the cultivar in full bloom.

FIG. 2 shows the various stages of bloom of the new cultivar;

FIG. 3 shows the various stages of foliage and petiole of the newcultivar.

DESCRIPTION OF THE INVENTION

This new variety of chrysanthemum is of the botanical classificationdendranthema grandiflora. The observations and measurements weregathered from 64 days plants grown in a greenhouse in Rijsenhout Hollandin a photo-periodic controlled crop under conditions generally used incommercial practice. The greenhouse temperatures during this crop wereat day-time between 18° C. and 25° C. and at night 20° C. Thephoto-periodic response time in this crop was 48 days after an averageof eight long days. After this long day period to flowering growthretardants were applied 6 times in an average dose of 1.5 gram/literwater. No tests were done on disease or insect resistance orsusceptibility. This new variety produces medium sized blooms withyellow ray-florets and yellow-green disc-florets blooming on the plantfor 5 weeks. This new variety of chrysanthemum has been found to retainits distinctive characteristics throughout successive propagationshowever the phenotype may vary significantly with variations inenvironment such as light intensity and temperature. To show thephenotype as described ‘HOGGAR’ can be planted without assimilationlightning (high pressure sodium lamps) between week 50 and week 40 ofthe next year under greenhouse conditions in Holland. With assimilationlightning (minimum level 2500 lux) it can be planted year round undergreenhouse conditions in Holland.

From cultivars known to inventor not one has a bronze underside incombination with yellow ray-florets. This is a special distinguishingcharacteristic of ‘HOGGAR’. The most similar existing cultivar incomparison to ‘HOGGAR’ is ‘Miramar’ (U.S. Plant Pat. No. 7,469). When‘Miramar’ and ‘HOGGAR’ are being compared the following differences arenoticed: Obvious differences of ‘Miramar’ and ‘HOGGAR’ are the bud colorand the bronze underside of the yellow ray-florets. In vigour, plantsize and flower size ‘HOGGAR’ and ‘Miramar’ are comparable.

The following is a description of the plant and characteristics thatdistinguish ‘HOGGAR’ as a new and distinct variety.

The color designations are taken from the plant itself. Accordingly, anydiscrepancies between the color designations and the colors depicted inthe photographs are due to photographic tolerances. The color chart usedin this description is: The Royal Horticultural Society Colour Chart,edition 1995.
